11 Automatic Startup and Stop (Standby) of 14 Rapid and Precise Sample Setting
Device is Possible

The X-ray unit can be automatically started up by registering The swing arm system sets a sample precisely within 5 seconds,
the device startup date and time in advance. in a single motion. This simple design minimizes down time and
Automatic stop (standby) can be set in the same way. ensures stable performance even in high-duty operation.
